2. Outline Design Context Senior Design Options Sample Projects Self-Evaluation Panel Discussion

3. Definition – Senior Design Course A Senior Design Course must provide students with a major multi-disciplinary design experience based on the knowledge and skills acquired in earlier course work. The design project must be team-based and must incorporate engineering design standards and realistic constraints that include most of the following considerations: economic; environmental; sustainability; manufacturability; ethical; health and safety; social; and political. The experience must also reinforce the students’ understanding of ethical and professional responsibility and their ability to communicate effectively.

4. Definition – Major Design Experience A major design experience is one that involves at least three (3) credit hours of coursework with 100% engineering design content and involves most of the following elements of the design process: the establishment of objectives and criteria synthesis analysis construction testing evaluation

5. Senior Design Learning Outcomes A student who successfully fulfills the course requirements will have demonstrated: 1.an ability to apply knowledge obtained in earlier coursework and to obtain new knowledge necessary to design and test a system, component, or process to meet desired needs. 2.an understanding of the engineering design process. 3.an ability to function on an interdisciplinary team. 4.an awareness of professional and ethical responsibility. 5.effective communication skills, both oral and written. Successful demonstration of all five learning outcomes is required to receive a passing grade.

6. Senior Design Reports  Summary of the project, including customer, purpose, specifications, and a summary of the approach.  Description of how the project built upon the knowledge and skills acquired in earlier ECE coursework (include course numbers).  Description of what new technical knowledge and skills were acquired in doing the project.  Description of how the engineering design process was incorporated, with reference to: establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation.  Summary of how realistic design constraints (economic, environmental, ethical, health and safety, social, political, sustainability, and manufacturability) were incorporated.  Description of the multidisciplinary nature of the project.

15. EPCS 401/2 – Senior Participation in EPICS Description: Uses service-learning to teach design within vertically integrated and multidisciplinary teams that design, develop, deploy and support projects that meet the needs of their local community partners. Objective: To provide long-term, authentic design experiences that exposes students to the entire design process from problem identification to support and retirement/disposal within a community/human context. Senior Design: Senior design students are distributed on EPICS teams with appropriate project potential and fulfill additional requirements to verify outcomes.

16. EPCS 401/2 – Senior Participation in EPICS Main Features: – Service-Learning Model Real projects for real people – Experience the entire design cycle – Multi-semester projects Senior design is a two semester experience for 3 credits with individual documentation and presentation requirements – Large (~15 students) and diverse teams with 3-5 active projects – Professional development: Leadership; Project management; Personnel and placement; Customer relations; Budgets; Technical reviews and Delivery Extensive communication requirements Ethics and social context Entrepreneurship and innovation – Formative and summative assessments of teams and individuals

17. EPCS 401/2 – Sample Projects EPICS Projects are done in four broad community areas – Human Services Information management, improved services – Access and Abilities Technology for adults and children with disabilities – Environmental Remediation designs, community education – Education and outreach Designs for schools, local museums and zoos Student perspective – Jaclyn Kollar Co-team leader for the Imagination Station Team – Local children’s science – Distributed sensor network

18. EPCS 402 – Example: Jaclyn Kollar Sensor Network Project for the Imagination Station Museum

19. EPCS 401/2 – Senior Participation in EPICS Ways to partner with EPICS: – Advise teams Weekly advisors for local corporate partners – Design reviews 11 th week of each semester – 4 teams per day – Workshops or lectures Technical and professional development topics during the semester – Sponsor a team EPICS does not charge the community for their work – Financial support for program Multidisciplinary support, dissemination, high school initiative – Awards for excellence

20. ECE 477 – Digital Systems Design Project Description: A structured approach to the development and integration of embedded microcontroller hardware and software that provides senior-level students with significant design experience applying microcontrollers to a wide range of embedded systems. Objective: To provide practical experience developing integrated hardware and software for an embedded microcontroller system in an environment that models one which students will most likely encounter in industry.

21. ECE 477 – Digital Systems Design Project Main Features: – One semester design / fabricate / test / demonstrate – Students pick own project (subject to constraints) and define own project-specific success criteria – Work in teams of four (mixture of ECE and CmpE students) – Design components include: packaging design, schematic design, printed circuit board design, and software design – Professional components include: design constraint analysis, reliability and safety analysis, patent liability analysis, and ethical and environmental impact analysis – Individual (on-line) laboratory notebooks – Extensive reporting/presentation requirements – Technical communication skills development activities – Quantitative assessment of all five course outcomes

22. ECE 477 – Sample Project The Wirelessly Integrated Menu System (WIMS) Aaron Replogle, ECE 477 Student Fall 2006 The WIMS is a portable device designed to input restaurant patrons’ food and beverage orders from a customizable menu and output them to the kitchen – Card reader input allows user identification – WiPort module allows transmission of data across wireless network to display an order queue in the kitchen – Touch screen LCD provides a simple method of navigating menus and accepting orders – Microcontroller unites the above peripherals, controls program flow, and interprets user survey data to create customized menus – [DEMONSTRATION VIDEO]

23. ECE 477 – Student Perspective The major hurdle for design teams is finances – Major design-specific costs – Parts – Development tools / kits Suggestion for further industrial involvement: – Possibility of design review and critiquing by engineers currently in industry Teams could provide project overview, schematic, and PCB layout for critiquing Toward the end of the semester, one or two teams could be recognized as having an “industry ready” project, while helpful comments could be provided to all teams

24. Self-Evaluation Strengths – Good diversity of design experiences afforded by current options available to students – Research/publications on outcome assessment Areas for Improvement – Development of a common senior design course evaluation instrument – More consistency in outcome assessment among the various senior design options – More consistency in project deliverables and their evaluation

25. Panel Discussion Opportunities for input – How well are the various ECE senior design options preparing students for the future? – What are (other) potential areas for improvement? Opportunities for involvement – Crafting ideas for senior design projects – Participating in the formal evaluation process – Supporting parts acquisition and PCB fabrication
